How do self blinking LEDs work?
The circuit for blinking an LED using transistors is called an Astable Multivibrator. The two capacitors C1 and C2 will alternate between being charged and discharged and thereby turning the transistors ON and OFF. When a transistor is ON it allows current to flow through it so that the LED above it will light up.

Can you simulate lightning?
In direct lightning tests, the simulator is connected to an object or arcs to it to simulate a lightning strike. In indirect tests, the lightning current is close by but doesn’t actually strike the object. This lets researchers study how magnetic fields generated by the nearby strike affect test objects.
What kind of light is lightning?
Lightning is visible as a flash of blue-white light. The extremely high temperatures generated heat the air molecules to a state of incandescence (white hot) such that they emit a vivid white light.
How do you make LED lights blink slower?
Most circuits use resistors to control LED blink rate. Once you find where the resistors that control the blink rate are located, you can adjust the resistors’ value for a slower blink rate. Obtain the schematic of the LED flasher circuit you want to stop the LEDs from blinking too fast.
